Masking lips

[RoberFranco93]

Hello everybody, I was trying to do add a mask to a mouth, I know the usual process for simple mouth shapes, but the mouth I've drawn contains coloured upper and lower lips. The problem here is when I mask it you can see the teeth between the lips so they become transparent but I want them be shown only in the hole between the lips.

I'm still learning how to use masks myself, but this works for me:

Mouth (Switch Layer)
>> MBP (or whatever phoneme you want; Group Layer)
>>>>Lips (choose "Don't Mask this Layer")
>>>>Inside Mouth (choose "Mask this Layer"; teeth go here)
>>>>Mask (choose "+ Add to Mask"; the shape of the mouth hole goes here)

Repeat for each phoneme.

Hope this helps.

Welcome to the forum.

So you mean that I should make a layer for the hole which is the throat and another one for the lips? I had that idea but I thought you could do it simpler because when you make it another shape for the switch layers you have to modify both layers, is it that right?

Yes, that's right, you would have to modify the lips layer and the mouth-hole layer separately. If you discover a way of doing what you want with fewer layers, please post the solution, because I'd like to know.
